How You Can Correct Glare On Eyeglasses In Illustrator Cs

How to Correct Glare on Eyeglasses in Photoshop CS


Proper photography requires that a scene be sufficiently lit. Commonly, lighting is added to a scene through the use of an on-camera flash. Unfortunately, these flashes tend to reflect in your subjects' glasses, causing unattractive bright highlights on their eyes. While there is no automated way to remove glare on eyeglasses in Photoshop CS--such as for red-eye removal--a few of Photoshop's tools can be used to help correct the problem of glare.


Instructions


1. Open the photograph you wish to correct in Photoshop by clicking on the "File" menu and choosing "Open." Navigate to the file you want to fix, click on it to highlight it and then click "Open."


2. Access the "Image" menu and choose the "Adjustment" option and then "Levels." The Levels window will display a histogram (graph) of the distribution of light and dark pixels in your image. Drag the left arrow inward to the bottom of the graph. This will remove any overall glare from the glasses, leaving only the completely overexposed areas.


3. Click on the "Lasso" tool, and click and drag your cursor around the glare to make a selection around the glare.


4. Open the "Select" menu, choose "Modify" and then "Expand." The value you expand your selection by will depend on the size and resolution of your image, however an expansion of approximately five pixels will usually suffice.


5. Return to the "Select" menu, choose "Modify" and then "Feather." Enter the same value by which you expanded your selection minus two. For instance, if you expanded your selection by five, enter three pixels as the feather radius.


6. Click on the selection and drag it to an area of the photograph that is similar in color and texture to the overexposed area. This will move the selection to that area. Good areas include the same spot on the subject's face in the other lens of the eyeglasses, or another spot within the same lens.


7. Access the "Layer" menu, click "New" and then "Layer via copy." This will copy your selection and paste it onto a new layer.


8. Click and drag the graft you created back to the area with glare. Position the graft over the glare to replace it with the patch of skin.


9. Right-click the patch of skin and choose the "Transform" option. Resize, rotate and skew the graft by dragging the corners of the selection box around the patch until it fits neatly within the glared area.


10. Click the "New adjustment layer" button and the "Hue/Saturation" option. Move the Hue and Saturation sliders left and right until the patch of skin matches the areas of skin around it. You will likely not have to move the sliders far.
